Most of the time, my codfish ended up broken after being squashed by the tong or while flipping the Happycall pan. So, after experimenting a few times, I decided to flipped once using a tong. And, I am using chunks of codfish that's trimmed off the bones.

You need to heat up a very hot pan, put your codfish skin down. Immediately, reduce to small fire, cover the lid and fry until the skin does not stick onto pan. Then, it is ready to flip ONCE. After its been cooked thoroughly, it will break apart easily so please use a spoon or ladle to transfer the codfish onto a plate before pouring the teriyaki over it.
